Dipolar optimal control of entangled current states
Héctor Briongos-Merino, Felipe Isaule, Bruno Juliá-DÃaz +1
Quantum state control is a fundamental tool for quantum technologies. In this work, we propose and analyze the use of quantum optimal control to exploit the dipolar interaction of…
Mobile impurity interacting with a Hubbard chain and the role of Friedel oscillations
Felipe Isaule, Abel Rojo-Francà s, Duc Tuan Hoang +3
This work examines a mobile impurity interacting with a bath of a few spin- and spin- fermions in a small one-dimensional open lattice system. We study ground…
Enhancing supercurrent-based inertial sensing via interactions in atomtronic angular accelerometers
S. Carmona-López, A. Matos-Abiague, F. Isaule +1
We theoretically investigate supercurrents of ultracold atoms in angularly ac-shaken ring lattices subjected to external rotation. Our results demonstrate how these supercurrents c…
Few-body bound states of bosonic mixtures in two-dimensional optical lattices
Matias Volante-Abovich, Felipe Isaule, Luis Morales-Molina
We study the formation of bound states in a binary mixture of a few bosons in small square optical lattices. Using the exact diagonalization method, we find that bound clusters of…
Counterflow of lattice polarons in harmonically confined optical lattices
Felipe Isaule, Abel Rojo-Francà s, Luis Morales-Molina +1
We study a mobile impurity in a one-dimensional harmonically confined optical lattice interacting repulsively with a bosonic bath. The behavior of the impurity across baths with su…
Dipolar magnetostirring protocol for three-well atomtronic circuits
Héctor Briongos-Merino, Felipe Isaule, Montserrat Guilleumas +1
We propose a magnetostirring protocol to create persistent currents on an annular system. Under this protocol, polar bosons confined in a three-well ring circuit reach a state with…
